The CDC337DWRG4 (hereon referred to simply as the CDC337 or 337) is a commercial class Clock/Timing product. It is designed to serve as a buffering, reproducing, and drive device for a clock signal source. The CDC337 is one of the few devices on the market which has been developed and manufactured for this specific purpose. It is highly reliable and suitable for long-term use, with a wide operating temperature range and low power consumption.

The 337 is a clock multiplier device that can double, divide, or otherwise multiply clocks or signals from a variety of sources. It is designed to take in a single clock source and reproduce its signal in the form of multiple copies of the same clock, all in sync with each other. It can also be used to divide a single clock by two or more, providing multiple signals at lower rates than that of the original clock.

The CDC337 has two main functional blocks: the clock buffer, and the clock distribution network. The clock buffer takes the input clock signal and reproduces a set number of the same clock signals, which are distributed through a slew of pins. The clock distribution network then takes these signals and provides low-jitter, highly accurate outputs for any crystal clock source.

An advantage of the CDC337 is that it provides an extreme amount of flexibility when it comes to clock inputs, as it can handle a wide range of frequencies, from 50 MHz down to DC. It can also be used in different environments and required voltages, including 3.3V, 2.5V, 1.8V, and 5V. This allows it to be used in multiple applications, including communication, consumer, automotive, and military.

Additionally, the CDC337 is an all-in-one clock driver device, meaning it will drive both input and output clocks, as well as a wide variety of other clock signals. It will also buffer data-input as well as clock-input and output. This makes the 337 versatile and makes it suitable for complex applications, such as those in analog recording and processing.

The CDC337 has a high-resolution modulation capability, allowing it to finely adjust the output clock frequency for extremely accurate timing. Additionally, it can be synchronized to a source and locked to an external reference in order to maintain absolute accuracy when working with multiple clock sources.

The CDC337 is designed to be robust and offers several levels of protection: it is immune to power transients and board noise, and has multiple ESD protection layers. The 337 also has EMI and ESD protection, as well as built-in thermal protection. Finally, it is available in a space-saving, lead-free package with minimal power requirements.

The CDC337 is an ideal choice for any application that requires reliable, accurate, and low-jitter clock transmissions and data buffering. Its wide range of features makes it suitable for use in many different applications and its reliability ensures that it can be trusted to perform accurately, even in tough conditions.
